Answer:

16x^7+13x^3+2

Step-by-step explanation:

8x^3+9x^7+5x^3+2+7x^7

Add 8x^3 and 5x^3 (don’t add the exponents together )

13x^3+9x^7+2+7x^7

Add 9x^7 and 7x^7

13x^3+16x^7+2

Then put them in order from biggest exponent to smallest

How would i solve for x and y in 3x+2y=17 and 2x-y=2 by using substitution
maxonik [38]
I’ll do an example problem, and I challenge you to do this on your own!
4x+6y=23
7y-8x=5
Solving for y in 4x+6y=23, we can separate the y by subtracting both sides by 4x (addition property of equality), resulting in 6y=23-4x. To make the y separate from everything else, we divide by 6, resulting in (23-4x)/6=y. To solve for x, we can do something similar - subtract 6y from both sides to get 23-6y=4x. Next, divide both sides by 4 to get (23-6y)/4=x.

Since we know that (23-4x)/6=y, we can plug that into 7y-8x=5, resulting in
7*(23-4x)/6-8x=5
= (161-28x)/6-8x
Multiplying both sides by 6, we get 161-28x-48x=30
= 161-76x
Subtracting 161 from both sides, we get -131=-76x. Next, we can divide both sides by -76 to separate the x and get x=131/76. Plugging that into 4x+6y=23, we get 4(131/76)+6y=23. Subtracting 4(131/76) from both sides, we get
6y=23-524/76. Lastly, we can divide both sides by 6 to get y=(23-524/76)/6

Good luck, and feel free to ask any questions!

31/6 as a mixed number
liubo4ka [24]
Hello there awesome brainly user!

To convert \frac{31}{6} to a mixed number you have to divide 31/6 which equals 5 R 1 Remember that the remainder is the numerator and the whole number is 5. So, the mixed fraction is 5\frac{1}{6}

For further info, message me

Thanks and have a good day.
